#[repr(C)]
pub struct RawWireUnion<'buf> { /* private fields */ }

A raw FIDL union

Implementations

impl<'buf> RawWireUnion<'buf>

pub fn encode_absent(slot: Slot<'_, Self>)

Encodes that a union is absent in a slot.

pub fn encode_as<E: Encoder + ?Sized, T: Encode<E>>( value: &mut T, ord: u64, encoder: &mut E, slot: Slot<'_, Self>, ) -> Result<(), EncodeError>

Encodes a value and ordinal in a slot.

pub fn encoded_ordinal(slot: Slot<'_, Self>) -> u64

Returns the ordinal of the encoded value.

pub fn decode_absent(slot: Slot<'_, Self>) -> Result<(), DecodeError>

Decodes an absent union from a slot.

pub fn decode_unknown<D: Decoder<'buf> + ?Sized>( slot: Slot<'_, Self>, decoder: &mut D, ) -> Result<(), DecodeError>

Decodes an unknown value from a union.

The handles owned by the unknown value are discarded.

pub fn decode_as<D: Decoder<'buf> + ?Sized, T: Decode<D>>( slot: Slot<'_, Self>, decoder: &mut D, ) -> Result<(), DecodeError>

Decodes the typed value in a union.

pub fn null() -> Self

The null (absent) union.

pub fn is_some(&self) -> bool

Returns whether the union contains a value.

pub fn is_none(&self) -> bool

Returns whether the union is empty.

pub fn ordinal(&self) -> u64

Returns the ordinal of the union.

pub fn get(&self) -> &WireEnvelope<'buf>

Gets a reference to the envelope underlying the union.

pub fn get_mut(&mut self) -> &mut WireEnvelope<'buf>

Gets a mutable reference to the envelope underlying the union.
